A solid conducting sphere of radius 10 cm is enclosed by a thin metallic shell of radius 20 cm . A charge q = 20 mu C is given to the inner sphere is connected to the shell by a conducting wire.

A solid conducting sphere of radius 10 cm is enclosed by a thin metallic shell of radius 20 cm . A charge q = 20 mu C is given to the inner sphere is connected to the shell by a conducting wire.

A solid conducting sphere of radius R is surrounded by a concentric metallic shell of inner radius 2R and outer radius 3R. The shell is earthed. The inner sphere is connected to a switch S by a thin conducting wire through a small hole in the shell. By closing the switch S, the inner sphere is connected to a distant conducting sphere of radius R having charge Q. Find the charge that flows to earth through wire AB.

A sphere of radius 10 cm conecentrically surrounded by a thin spherical shell of radius of 11 cm A charge of 100muC is imparted to the outer spheree and the inner one is earthed. Calculate the charge on the outer surface of the inner sphere and on the two surfaes of the outer sphere.

A solid conducting sphere of radius a is enclosed in a concentric shell of radius b gt a . The charge on the inner sphere is 3muC and on the conducting shell is -10muC . The potential difference between the conductors is V. If +10muC additional charge is given to the outer shell, the new potential difference is

Figure shows a solid conducting sphere of radius 1 m. enclosed by a metallic shell of radius 3 m such that their centress coincide. If outer shell is given a charge of 6 mu C and inner sphere is earthed, find megnitude charge on the surface of inner shell
